Master of Thermodynamics
Chapter 268
Renault''s unexpected idea to "invent" ice cream is related to a batch of gifts he has just received.
Evans, Hyde, Bentley and others don''t know where to find out that Renault is a gourmet master and likes to make delicious food by themselves. So before Renault''s departure, they spared no effort to collect a large number of precious food materials and packed two large wooden cases.
One of them is a can of black sugar weighing 10 kg.
Although this kind of black sugar doesn''t sell well, there are many impurities and the sweetness is not enough, it is definitely a sincere gift.
Because this can of black sugar alone is worth more than 15 jinnals.
In the alien world, there are no sugarcane, beet and other plants that can extract sugar on a large scale. It is very difficult to obtain sugar. This kind of black sugar comes from a shrub called "black honey tree".
To be exact, it comes from its fruit and seed.
Note that it''s the seed, not the fruit.
In order to extract black sugar, we must first pick the black honey fruit from the black honey tree, then peel off the seeds, and then get the syrup by boiling in water. After it is dried, we get black sugar.
The growth environment of black honey tree is harsh, with few fruits and fewer seeds, so the yield of black sugar is very low.
The price of black sugar is so high that even ordinary nobles can''t afford it.
At the first sight of black sugar, Renault''s obsessive-compulsive disorder broke out instantly, and he immediately had the idea of refining white granulated sugar.
Good sugar, black like what words?
This cliff can''t stand it!
It has to be refined.
With his ability, it''s easy to do that.
The black sugar is melted into sugar water. After repeated filtration, the impurities are removed. Then the clarifier, i.e. lime, carbon dioxide and activated carbon, is added to remove the pigment. After the color of the sugar water is nearly transparent, the water is evaporated to dry, and the white granulated sugar is as white as snow.
This kind of white granulated sugar is not only more pure, but also more sweet, which is very suitable for making desserts.
After thinking about it for a while, Renault decided to "invent" ice cream first, because it is made in the simplest way.
White granulated sugar, eggs and milk are the raw materials of ice cream. As for the specific steps, it is as easy as hand for Renault.
egg yolk with white sugar, stir into egg paste, pour it into milk, heat it to a certain temperature, continue stirring, and turn it into a thick emulsion, then freeze and cool down. In this process, we must continue stirring. At this step, ice cream is formed.
The key to making ice cream is to "stir.".
Looking back at the production process, you will find that it''s just like stirring from the beginning to the end, with almost no pause.
Why do you have to stir?
Because when stirring, the air will be evenly mixed with protein, fat and water to form a cream like semi-solid mixture, which is called "puffing" in professional terms.
It can also be understood that there are very few "dry goods" in ice cream. What''s special in ice cream is "air" and "water", which is more than puffed food like potato chips.
At least the puffed food didn''t add water, did it?
But it is precisely because of its "less dry goods", the taste of ice cream has become so smooth and delicate.
Because protein, fat and water make up countless tiny "cages", trapping a large number of "air molecules" in the cages, forming a loose and porous structure.
When tasting ice cream, every time the tongue licks up, the cage breaks, the trapped air molecules are released, and the tongue is gently massaged, so it has a "delicate" taste.
In fact, making ice cream by hand is very troublesome and laborious. NIMA keeps stirring, even Kirin''s arm will feel tired.
It''s not a matter in the face of mindfulness.
under the control of Reynolds, the speed of mixing is absolutely constant, which makes the mixture of emulsion and air more uniform, and the ice cream produced by Jean Reno has a better taste.
When the three girls stepped into the cabin, they saw the ice cream that had just finished the expansion process. Renault had not cooled it yet.
Under the gaze of the girls with a look of novelty and expectation, Renault moved a new empty container with his mind and put it next to the glass jar.
Then he flicked his fingers. A dozen baby fist sized ice cream balls floated out of the glass jar, flew to the empty container and hovered inside.
The three girls were surprised and confused.
is surprised that the appearance of ice cream balls is so cool that they suddenly pop out of a bunch of white flowers and roll in the air for a few turns and then become perfectly spherical. This is a magic trick.
What''s more, why did the LORD put the ice cream ball into the empty container?
There seems to be some strange change on the surface of the ice cream ball, and the color obviously changes slightly. Is this some mysterious ceremony?
What kind of food is the ice cream your Lord wants to make? Even using rituals?
Although they were quite puzzled, no one dared to ask. On the contrary, they were filled with awe.In fact, their idea is not wrong. What Renault is doing now can barely be regarded as a kind of ceremony.
But it''s not mysterious at all. It''s just cooling down. What''s the mystery?
This is another of Renault''s unique ice cream making skills - low temperature quick freezing.
On earth, some high-end restaurants use liquid nitrogen to make ice cream for rapid cooling.
Why use liquid nitrogen?
To show off?
Or use the more expensive liquid nitrogen as a selling point?
Of course not.
The purpose of using liquid nitrogen is to improve the taste.
During freezing, the liquid water in ice cream will form ice crystals, and the smaller the ice crystals, the better the taste of ice cream.
It''s easy to understand. If the ice crystal is very big and the water in the ice cream turns into ice slag, would you like to eat it?
Of course not.
If you take a bite, your mouth hurts. Whoever likes to eat will eat. Anyway, labor and capital don''t want to eat.
However, in the case of low-temperature quick freezing, more than 80% of the free water will quickly condense into ice crystals, so there is no time to combine into large pieces of broken ice. Moreover, the lower the temperature is, the smaller the ice crystals are, and the better the taste is.
The temperature of liquid nitrogen is close to minus 200 degrees. When ice cream is soaked in liquid nitrogen, the ice crystals formed are very small, which greatly improves the taste.
With the ability of reverse heat conduction, Renault can easily produce super low temperature, not to mention minus 200 degrees or minus 250 degrees. Therefore, the delicacy of the ice cream made by Renault is beyond the horizon.
It''s a pity that only those who are familiar with the method of making ice cream can have a deep understanding of the great power of the great chef. The three girls don''t know what ice cream is, and they have no idea about it. Renault''s performance can be described as a bright shot in the dark.
More than 30 seconds after quick freezing, Renault waved his hand. More than a dozen ice cream balls were divided into four piles and fell into four delicate silver bowls. After repeating the operation twice, each silver bowl was full of ice cream balls.
Then he said with a smile:
"try the ice cream first..."
Before the words were heard, the silver bowl floated to each girl''s eyes automatically. Beside the silver bowl, there was a silver fork floating, which was accompanied by a more intense sweet smell, making people greedy and crazy.
Three girls foolishly took the silver bowl, couldn''t wait to fork up a snow-white ice cream ball, put it into their mouth, and bit it gently.
Then, a performance called "face changing" appeared on every girl''s pink face.
When the three lips touched the ice cream ball, they could not help shivering and frowning.
It''s so cold!
Is this the ritual your Lord used to make ice cream?
When their tongue touched the ice cream ball, their pretty faces showed great surprise.
God, what kind of food is this?
It''s incredibly soft.
It''s exquisite beyond imagination.
It''s something they''ve never felt before.
When the ice cream rolls in the mouth and touches the sweet taste sensing cells at the base of the tongue, the surprise on their tender faces turns into a kind of deep happiness.
The rich sweetness mixed with strong milk flavor was a taste they had never experienced before, and it also completely activated their nerve center and promoted their brain to secrete a large amount of dopamine, which made them feel a kind of sincere happiness.
In one sentence.
This is the taste of happiness.
The ice cream that the girls thought was incomparably delicious just satisfied Renault.
He prefers yogurt ice cream. He also thinks that ice cream without fruit is not perfect.
Therefore, he pays more attention to the beautiful scenery than the delicious food.
Looking at the three delicate beauties sipping the ice cream, their faces are full of extreme enjoyment. Under the snow-white background, the three red and tender pink lips add an indescribable allure, making Renault have a strong impulse to kiss.
He sighed contentedly in his heart.
Well, it''s an afternoon to look forward to.
The coming night is even more exciting
